Lamb of God have cancelled their upcoming co-headline tour with Dethklok scheduled to begin on 1 August in Seattle due to the incarceration of their singer Randy Blythe in the Czech Republic. The also means Lamb of God will not be appearing at the HEAVY T.O. and HEAVY MTL festivals taking place on August 11th at 12th in Toronto and Montreal, however, Dethklok and Gojira will still be playing these dates. In Flames have been added to the roster for both Heavy dates as a stand-in.

Randy Blythe was arrested by police on suspicion of manslaughter upon arrival in the Czech Republic on 27 June. Lamb of God were set to play in Prague the following day. Blythe’s arrest last month comes after being charged with manslaughter in connection with the death of a fan at a concert in 2010.

The manslaughter charges stem from an incident on 24 May 2010, when Lamb of God were performing at Prague’s Klub Abaton. A 19-year-old fan, Daniel Nosek, tried to get onstage, Blythe allegedly pushed him off; his head hit the concrete floor and he later died from his injuries.

Czech news service Novinky reported with a quote from Lamb of God’s management that Nosek repeatedly “invaded” the stage. “The incident has to do with a fan that crossed three times during the concert and harassed Randy during the performance. Apparently the third time security was not able to catch and guard him so Randy put him back into the audience, where he apparently fell on his head, “said Maria Ferrero, Adrenaline PR publicist.

Blythe’s bail was originally set at 4m Czech koruna (£130,000/$205,00), then after a challenge by prosecutors, was doubled to 8m koruna (£250,000/$410,000). However, in court on Wednesday, Czech prosecutors again challenged the musician’s release calling him a “flight risk”, with the concern being that if allowed to fly home to the USA he would not return to the Czech Republic for trial.
